protective, fatty layer insulating nerve cell axons for rapid signal transmission
The myelin sheath is a protective, fatty layer that surrounds the axons of nerve cells, acting like insulation around electrical wires. This sheath is crucial for the rapid transmission of electrical signals along the nerve cells, enabling efficient communication within the nervous system. Damage to the myelin sheath, as seen in conditions like multiple sclerosis, can disrupt these signals and lead to neurological problems.
